|This is the plot
we showed earlier, but with Ri next to the time-depth transects. Ri at the
pycnocline near 120 m is less than 1, and so we think mixing might be
|Once we have a
Ri, we can estimate diffusivities and then heat fluxes, using
parameterizations such as Pacanowski and Philander. We find that the region of low Ri produces
an upward heat flux of 25 W m-2.
